Title: Improvements in or relating to apparatus for separating and removing liquids from a stream of gas
IPC: F16N7/34
Filed: 1951-12-03
Abstract: 710,663. Steam traps. AKTIEBOLAGET SVENSKA KULLAGERFABRIKEN. Dec. 3, 1951 [Dec. 27, 1950], No. 28331/51. Class 64(2) In a device of the steam trap type for removing a liquid from a gas under pressure (such as water condensed from com-. pressed air), a liquid-separating chamber 1 is connected to a gas pressure line by an inlet 2 and an outlet 3. Moreover, the chamber 1 communicates through a reducing valve 11 with a control chamber 14 having one or more outlets 17, 18, Fig. 2, for the liquid, the valve 11 being controlled by the pressure in the chamber 14, through a membrane 21. The reducing valve is a ball 11 interposed between a spring 10 on one side and a sliding pin 20; the membrane 21 and a spring 25 in a chamber 24, opening to atmosphere by a hole 31, on the other side. A saucershaped disc 26 is mounted between the membrane 21 and spring 25. With atmospheric pressure in the annular chamber 14, the ball 11 is depressed to allow flow from an intermediate chamber 13 (fed from a tube 7 in the chamber 1) through a duct 12 to the chamber 14. Air, from the inlet 2, impinges against a cylindrical skirt 5 so that water separates and falls to the bottom of the container 1. Some of the air, instead of flowing through the outlet 3 passes through a strainer 8 and up to the. tube 7 to find its way, eventually, out through the holes 17, 18 to an outlet pipe 19, Fig. 2. Increase in pressure of the air in the chamber 14 raises the membrane 21 to move the ball 11 to closure and when the.pressure drops again the ball moves to opening thus tending to maintain a pressure in the chamber 14 below that of the main air stream. When the collected water reaches the level of the filter 8 it passes up the tube 7 through the chamber 13 and duct 12 to the chamber 14 whence it flows to the outlet pipe 19 through the hole 17. The air continues to escape through the hole 18 unless that outlet serves to carry away an excessive water flow. Any impurities are drawn off when necessary through a duct 27 by loosening a nut 29 to displace a ball valve 28. In one modification, Fig. 3 (not shown), the trap is inverted, the tube 7 is omitted and the air outlet 3 is at the top. In another inverted form; Fig. 4 (not shown), the skirt 5 and the openings 2, 3 are omitted, the top of a smaller chamber 1 being threaded for connecting to an existing container or to a pipe line. An extra container may be connected to the chamber 14 to increase the volume and the reducing valve may be at the side of the chamber 1.

Title: Process for finishing synthetic fibres
Inventor: DREHER ERICH
IPC: C08G69/48
Filed: 1964-07-10
Abstract: A finishing agent for synthetic fibres and fabrics comprises an aqueous solution of an ethenoxylated polyamide which is produced by reacting 1 part by weight of polyamide with 2.5-3.5 parts by weight of ethylene oxide at 80-100 DEG  C. and a pressure between 2 atmospheres gauge and the liquifaction pressure of the ethylene oxide and dissolving the product in water at 90-150 DEG  C.  The polyamide may be produced in the presence of an acid or neutral catalyst from pentamethylene diamine, hexamethylene diamine, and/or decamethylene diamine or salts thereof, adipic, pimelic, sebacic, terephthalic, phenylene diacetic or phenylene dipropionic acids or derivatives thereof having oxygen or sulphur in the carbon chain, o -amino-butyric, caproic, caprylic, capric, undecanic and dodecanic acids or lactams thereof. Their water content may be reduced to less than 1%.  Unreacted ethylene oxide may be recovered by restoring atmospheric pressure within the reaction vessel and condensing the issuing gas.  The ethenoxylated polyamide may be dissolved in the presence of a solubilizer, or oxidizing or reducing agent. Solubilizers specified are: ethanol, propanol, ethylene glycol, ethylene glycol monomethyl ether, T.H.F., dioxane, acetone, H2SO4, H3PO4, H3BO3, HCOOH, CH3COOH. 20-200% may be used.  0.05-1% H2O2 may be used as oxidizing or reducing agent.  Other suitable reducing agents are NaBH4 and sodium hypophosphite. The colloidal solution may contain 1-50% of the ethenoxylated polymer.  The water may be allowed to evaporate and the product redissolved in hot water.ALSO:The water-absorbency of fibres, fabrics and sheets may be increased by impregnating them with an aqueous colloidal dispersion of an ethenoxylated polyamide.  The solution is prepared by treating a polyamide with 2.5-3.5 times its own weight of ethylene oxide at 80 DEG -100 DEG C. and a pressure between 2 atmospheres and the liquifaction pressure of ethylene oxide and dispersing the reaction product in water at 90 DEG -150 DEG C. Polyamides specified include nylon 6/66 and nylon 6.20-50% of the ethenoxylated polyamide may be dispersed in water in the presence of a solubilizing agent, e.g. EtoH. 0.05-1% of an oxidizing agent, e.g. H2O2, or 0.05-0.5% of a reducing agent may also be present during dispersion.  The pH of the dispersion may be adjusted to 3-7, e.g. with acetic acid. The viscous or gelatinous dispersion may be diluted with water before impregnation to 1-10% concentration.  The impregnation may be at elevated temperature using a foulard or by steeping and drying.
